Volkswagen Passat engines & block heater part numbers
Engine list built from Natural Resources Canada model-year data. Part numbers are catalog candidates unless a source review is shown for that application. Confirm the exact engine code, model year and installation port before ordering; an Amazon listing match does not confirm vehicle fitment.

Reading the numbers: Zerostart 31/35- is the heater kit, 36- the detachable cordset ("lit" glows when the outlet is live). Kat's 11xxx is an element, 28xxx a cordset, 24xxx a pad. Location codes are the manufacturer's (LF = left front of block).

What it costs to plug in a Volkswagen Passat — and what it saves
No supplier lists a wattage for every Passat element, so this uses the 1000 W figure typical of this body style. Natural Resources Canada recommends a timer that runs the heater two hours before you drive rather than all night — that is what the numbers below assume.
| Province | ¢/kWh | Cost per 2 h plug-in | Full winter (120 nights) | Net per day |
|---|---|---|---|---|
| Quebec | 7.0 | $0.14 | $16.80 | +$0.26 |
| Manitoba | 10.2 | $0.20 | $24.48 | +$0.20 |
| Ontario (avg TOU) | 12.8 | $0.26 | $30.72 | +$0.14 |
| Alberta | 14.0 | $0.28 | $33.60 | +$0.12 |
| Saskatchewan | 15.5 | $0.31 | $37.20 | +$0.09 |
| Nova Scotia | 17.9 | $0.36 | $42.96 | +$0.04 |
Natural Resources Canada rates the Volkswagen Passat at 12.9 L/100 km in city driving (median across 1995–2022 model years). On a 20 km winter commute that is about 2.6 L a day. NRCan measured that at −20 °C a block heater improves overall fuel economy by as much as 10% — roughly 0.26 L, or $0.40 of gasoline at $1.55/L. On a single short trip at −25 °C the saving can reach 25%. In most provinces the electricity costs less than the fuel it saves; in the priciest it roughly breaks even, and you still get the wear, defrost and cabin-heat benefits.

Block heater recalls on the Volkswagen Passat
Transport Canada has recorded 2 recalls on the Passat that involve the block heater or its cord. Check your VIN before you buy parts — if your vehicle is affected, the repair is free.
Issue: On certain vehicles, the warning label for the engine block heater cable is written in English only. As a result, a French user may not receive important safety information about how to use the engine block heater. A label that is not provided in both official languages could create confusion. Safety Risk: User confusion could increase the risk of injury when trying to use the block heater. Corrective Actions: The company will mail each owner a new label for the block heater cable. If you would like help installing the label, you can contact a dealer for assistance.
On certain vehicles equipped with a factory installed block heater, the block heater could overheat while in use. This could result in a fire causing injury and/or property damage. Correction: Dealers will replace the block heater. Owners are advised to stop using the block heater in the interim.
IN THE EVENT OF AN ENGINE BACKFIRE DURING COLD START, AN AIR SCREEN WHICH IS LOOSELY SEATED IN THE AIR FLOW METER COULD BECOME DAMAGED. SHOULD THIS HAPPEN, SCREEN PIECES COULD ENTER THE INTAKE AIR FLOW SYSTEM AND COULD PREVENT THE THROTTLE PLATE FROM RETURNING TO ITS FULL IDLE POSITION. CORRECTION: A SCREEN RETAINING RING WILL BE INSTALLED AND DAMAGED SCREENS WILL BE REPLACED.

No tools? The stick-on option
If you'd rather skip the install entirely, a magnetic heater grips any flat steel surface — oil pan, block, transmission pan — and moves between vehicles. Check that the Passat's oil pan is steel first: a magnet won't hold on aluminum or composite pans.

First: check whether you already have one
Canadian-market vehicles are often fitted at the port or dealer and then forgotten by the next owner, so check the cord location above before you buy anything. If a cord is there, test it — a dead element and a dead cord look identical from the outside.
If you need one installed
Budget $40–$120 CAD for the part plus about an hour of labour, and book in October — Prairie shop calendars fill after the first cold snap.
